Specification of Letters Patent.

Patented Nov. 24, 190B.

Application flied March 12, 1908. Serial No. 420,631.

ties und the objects of my invention are, first,

to provide e novel concrete tie of a durable construction; second, to provide o. reinforced concrete tie that will withstand the stresses and strains set up by rolling stock passing over the same; and third, to provide novel fasteners for reteininff rails upon my tie.

I attain the above objects by n tie that will be presently described and then specifically claimed.

Referring to the drawingforniing partof this specification, Figure 1 is an elevation of my tie. Fig. 2 is e plan of the saine. Fig. 3 is a longitudinal sectional view of e portion of the tie, and I`i 4 is a cross sectional view ofthe seme, tagen on the lines :v -w of Fig.`3.. F ig. 5 is a horizontal sectional view of e portion of the tie, showing the embedded abutment plate for the bolt heads in plan.

To put my invention iulo practice, I provide a tie made of concrete end reinforced by metallic rods to add ri idity and strength' to the same. My tie is oblong and of dimensions similar to the present typeof wooden' ties, but I desire it to be understood that thev tie cen be made of any length according to the use of the same. i,

A suitable mold or machine is employed for making my tie, either in a factory rovided therefor, or in the vicinity of W ere the tie is to be used. My concrete ie is formed with recesses or cavities 1 and with seins 2 for rails 3. The recesses 1 serve to lighten thc tie and cheapen the construction thereof without i'n any manner weakening it. The seats 2 of the tie are provided with diagonally disposed recesses 4 and with narrow slots 4 which communicate with the rcccsses through one wall of the letter. The slots 4 et their lower ends commul'iicate with cavities 5 within the body of the tie, said cavities being also im communication with the recesses 4 at the lower ends of the latter, the lower part or portion of the recesses 4 and the cavities 5 together with the slots 4 forming substantiull the fastener bolts are received and held as will be later described. In the seats 2 are embedded slotted plates 2, these plates being arranged in the fastener recesses 4 at the lower ends of the slots 5.

T-sheped recesses in which The rail fasteners which I use in connection with my tie comprise base plates 6 having depending flanges 7 for restmg upon the -rml sont and providing e s ace between said plates and the seat, the ob ect of which will presently appear. These ase plates 6 are retained in enga ement with the rails 3 and the seats 2 by bo ts 8 and nuts 9. The bolts are placed in the recesses i with the heads 8 thereof downward, and are then moved Iso that the shank of the bolt passes into the slots 4: of the tie and the notch 2 of the plato 2a, the head 8 of the bolt be' received in the cavity 5. The plates are then placed on the threaded ends of the bolts und secured b the nuts l9. The plates 2 prevent the hee s of the bolts from cutting into the concrete.

The space between the rail seats and the plate 6 permits of. the nuts 9 being screwed upon the 'bolts 8 to force the plete 6 downwardly upon the base flanges of a. rail, thus obtainin a more positive grip u on the rail than if t e space'Y were notprovi ed.

My tieis reinforced by metallic members .preferably in the form of'twisted steel bars 10.` These twisted steel bars are arranged within the sides of the tie and in the bottom thereof, as illustrated in Fig. 4, thus providing a channel shaped reinforcement nda ted to fully protect` the tie.

aving now described my invention what I claim as new, is;-

A reinforced concrete tie having reilseats provided with diagonally-disposed vertical recesses, said seats also provi ed with narrow vertical slots communicating with the recesses and having cavities communicetin with the lower ends of the vertical slots un recesses, notched abutment plates embedded in said tie directly over said cavities wlth the notches therein registering with said vertical slots, bolts seated in said vertical slots In testimony whereof I flix my signature ind the notches in said plates with their in the presence of two Witnesses.

eads received in said cavities and engaging the plates, clamp plates received on Seidl JULIUS F' WEILEP 5 bolts to engage rails mounted on said seats, and nuts on the bolts Ato secure said clamps in position.
